Now the purpose of the Alchemist is to refine his soul to become in a highest state of being,the Soul re-incarnates through ages in order to achieve prefection to stop this cycle of birth death and rebirth,one must achieve the ultimate state of prefection,once this state is reached the soul stops reincarnation and experience ultimate enlightenment of uniting with the spirit of the creator.

this state is explained in the book of Duat as well as in the pyramid texts as the union with RAA in the final stage of the duat,the return to the ultimate source,that is light,for from light we come and to light we go,this process may take some a thousand years while others may have to go through the cycle of birth and death,through Aeons and Aeons,now to our loving SOL,the prefection.

the book of the dead specifically the part where you say I did not tell lies,I did not kill..is an expression of this higher consciousness,the prefection for one must be purified to rise to the eyes of RAA ,Osiris and Thoth are the ones who decide if that state of prefection is achieved or not,waking to the fields of Yalu or fall into the pit of hell I.e physical limitness in the body and 3 dimintional reality.
Immortality is the state of reaching prefection to unite with Raa and live as an immortal being,
Brothers of the art,refine your soul ,that's your key to immortality.The old view was that the sun dies,the new view was that the sun never dies but the earth revolving around itself makes it look so ,so the sun is always with us,the process of refining is made posible by the new view that will revolutionise the occult belief,in our search for truth we find many things but most of all we find our selves.

Peace and love
